To all whom it may concern:

Be it known that 1, JOHN XV. BELYEU, a citizen of the United States,residing at Alexander City, in the county of Tallapoosa and State ofAlabama, have invented certain new and useful Improvements in Gearing;

and I do hereby declare the following to be a full, clear, and vention,such as the art to which use the same.

My invention relates to new and useful improvements in controllingmechanisms for saw mills or similarly operated machinery and my objectis to provide a friction drive for the log carriage.

A further object is to provide means for reversing the operation of thecarriage drive.

A further object is to provide means for increasing or decreasing thespeed of the driving mechanism and a still further ob ject is to providesuitable adjustments for the parts of the driving mechanism.

ther objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings which are made a part of this application,Figure l is a perspective view of a portion of a saw mill, showing myimproved mechanism applied thereto. Fig. 2 is a side elevation of abracket employed for supporting parts of the driving mechanism. Fig. 3is an end elevation thereof. Fig. 4 is an end elevation of a slidingbearing for one of the parts of the driving mechanism. Fig. 5 is a sideelevation thereof. Fig. 6 is an elevation of a shifting bar and parts towhich the same is attached. Fig. 7 is an end elevation of a deviceemployed for shifting the bearing shown in Fig. 4. l thereof, and Figs.elevations, respectively, of a collar for supporting parts of thedevice.

eferring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates a frame,such as is commonly used in connection with saw mill constructions, saidframe having rotatably mounted thereon, a shaft 2, to one end of whichis secured a belt wheel 8 and to the opposite end thereof, the usual orany preferred form of saw 4. I11 mills of this class, the log is placedupon a carriage and brought into contact with the exact description ofthe in- Wlll enable others skilled 111 it appertams to make and saw 4,said carriage being driven through Specification of Letters Patent.Application filed November 10, 1908.

Patented Get. 12, 1909. Serial No. 481,908.

I the medium of a shaft 5, on which are placed suitable cogs, which areadapted to engage with cog racks on the log carriage, but as thecarriage and parts to drive the same, form no part of my invention, itis not deemed necessary to further describe the same.

Motion is imparted to the shaft 5 by placing thereon a cog gear 6, withwhich is adapted to mesh a pinion 7, carried on a shaft 8, one end ofthe shaft 8 being mount ed in a bearing 9, while the opposite endthereof has fixed thereto a friction wheel 10, the bearing 9 bearing 11,which bearingis bracket 12, carried between the the frame 1.

As that end of the shaft 8 containing the friction wheel 10, is adaptedto be swung laterally to bring the friction wheel into engagement witheither of the disks 13 or 1-1, carried by the shaft 2, the bearing 9 ismovably mounted between the lnfurQated end 15 of a stub shaft 16, saidshaft being in turn carried by one of the side members of the frame 1.

The bearing 9 is pivotally held between the bifurcated ends 15, byintroducing screws 17 through said ends and into enentered in a sidebars of gagement with the hearing, so that said earing may swinglaterally to compensate for the swinging movement of the shaft 8, whilethe stub shaft 16 is adjustably secured to the frame 1 by introducingthe end thereof into a socket 18 and providing a set screw 19 forholding the stub shaft in its adjusted position.

The sliding bearing 11 is provided in its base portion 20 with a slot21, which is adapted to engage a rib 22 on the bracket, said rib holdingthe bearing 11 firmly seated in the bracket 12 and at the same timepermitting said bracket to move laterally.

Formed in the upper portion of the bearing 11, is a recess 23, in whichis adapted to enter a stem 24, depending from a cylindrical body 25mounted upon a controlling shaft 26, said body being secured to saidcontrolling shaft in any preferred manner, as by means of set screws 27.

Extending upwardly from the bracket 12, are standards 28, between whichis located a collar 29, which collar forms a bearing for one end of theshaft 26 and is supported between the standards by means of bolts 30,the inner ends of which bolts are pointed the lever 35 is swunglaterally to the right until the friction wheel 10 is brought intoengagement with the disk 13 and as soon as the log carriage has beenreturned to its initial position, the lever 35 is immediately swung to avertical position, thus disengaging the friction wheel from both of thedisks and permitting the log carriage and gears which operate the sameto remain idle until such time as it is again desired to move the loginto engagement with the saw.

If, while the carriage is being moved for wardly or rearwardly, it isdesired to decrease the speed of the carriage, the lever 35 is thrownforwardly, thereby moving the friction wheel 10 toward the axial centerof the disk with which it is engaged, while, if it is desired toincrease the speed of the carriage, the lever 35 is thrown in theopposite direction or rearwardly and the friction wheel 10 moved towardthe outer edge of the disk, this action increasing the speed of thecarriage.

This device may be attached to any class of machinery where it isdesired to reverse the operation of portions of the same or drive themachinery at different speeds, but is more particularly adaptable foruse in connection with saw mill machinery and in view of thesii'nplicity of the device, may be very cheaply constructed andinstalled at a minimum expense and amount of labor.

\Vhat I claim is:

1. A device of the character described, comprising a shaft disks carriedthereby, an additional shaft a friction disk carried thereby arrangedintermediate of the firstreferred to disks and initially out ofengagement with said disks, the latter shaft also being provided with afixed hub member, a split collar embracing said hub member, a standardhaving connection with said split collar, a manually actuated lever, anda link connection between said standard and said lever.

2. A device of the character described, including a shaft spaced apartdisks carried thereby, a second shaft a friction disk carried therebyarranged intermediate of the aforesaid disks and initially out ofengagement therewith, a sleeve receiving the latter shaft having agroove in its lower surface, a frame member having a rib engaging saidgroove, said sleeve having a notch in its upper surface, a third shaft asleeve member thereonp-rovided with a pendent projection received bysaid notch and upstanding parallel members upon its upper surface, asleeve a manually actuated lever having pivoted connection with saidsleeve connected to the last-referred to shaft and a link connected tosaid shaft and received between the up-standing portions of said sleevememher.

3. A device of the character described,

and enter counter-shuts 31 in the face of the collar. The opposite endof the controlling shaft 26 is entered through a socket 32 in the endbar of the frame 1, the extended end of the shaft having fixed thereto aplate 83, to which is secured the bifurcated end 34 of a lever 35 and asthe lever 35 is pivoted to the plate at a point adjacent its connectionwith the shaft 26, a sufficient portion of the plate 33 will extendbetween the bifurcated end 34 to cause the shaft 26 to rotate when thelever 35 is swung laterally and as the body fixed to said shaft, therotation thereof will move the bearing 11 longitudinally of the rib 22and bring the friction wheel 10 into engagement with one of the disksbetween which the friction wheel is located, the object of shifting thefriction wheel, being to reverse the rotation of the shaft 8 and partsoperated thereby to move the log carriage 3(3 forwardly or rearwardly.

it is desirable at times to increase or decrease the speed of the logcarriage and to this end I have provided means for moving the frictionwheel 10 longitudinally of the shaft 8 and toward or from the axialcenters of the disks 13 and 14, consisting of a shifting bar 37, thelower end of which bar is bifurcated to straddle a split collar 38surrounding the hub 39 of the friction wheel 10, bolts 40 beingintroduced through the bifurcated ends of the shifting bar and intoengagement with the split collar, the inner ends of said bolts beingtapered and entered in cavities 41 in the collar.

The lever 35 is connected to the shifting bar 37 by means of a link 42,one end of the link being pivotally mounted between the bifurcated endof the lever, while the opposite end of the link is introduced through aslot 43 in the upper end of the shifting bar 37, said link being held inthe slot by means of a set screw 44, extending through the upper end ofthe. shifting bar and in position to bind on the upper edge of theinterposed portion of the link 42 and it will be readily seen that whenthe lever 45 is swung forwardly or rearwardly, the friction wheel 10will be moved toward or from the axial centers of the disks 13 and 14,the link 42 being entered between guide arms 45 extending upwardly fromthe body 25, said arms adding rigidity to the link and causing theshifting bar to rotate around the hub of the friction wheel when thelever 35 is swung laterally to reverse the travel of the log carriage.

In operation, when it is desired to move the log into engagement withthe saw, the lever 85 is swung laterally to the left, thus moving thefriction wheel 10 into engagement with the disk 14, the lever being heldin this position until the saw is passed entirely through the log oruntil such time as it is desired to reverse the log carriage, whensecond sleeve.
